"The following fishes were collected: Alert: Salvelinus alpinus; Gymnelis virdis; Icelus bicornis; Myoxocephalus quadricornis; Liparis koefoedi; Liparis ? liparis. Mould Bay: Salvelinus alpinus; Boreogadus saida; Anarhichas denticulatus; Lycodes pallidus; Icelus bicornis; Myoxocephalus quadricornis; Eumicrotremus spinosus. 2. Two different forms of catfish are currently referred to Anarhichas denticulatus, but it is not known whether the differences are due to sex, age, or other factors, or whether or not the differences are specific. 3. The specimens of Icelus bicornis listed by Walters (1953) from various stations in Dolphin and Union Strait, Northwest Territories, probably consisted at least in part of Icelus spatula; one specimen may have been Icelus bicornis. 4. Cottus polaris Sabine (1821) and Porocottus polaris (Sabine) Jordan and Evermann are identical to Myoxocephalus quadricornis (Linnaeus). 5. Eumicrotremus pacificus Schmidt is not identical to E. orbis (Günther). 6. The record of Eumicrotremus birulai from the Kara Sea (Popov, 1933) should be regarded as probably E. spinosus. 7. Eumicrotremus spinosus variabilis Jensen (1944) is identical to E. derjugini Popov (1926)"--P. 14-15
